787-790: LGTM! Consider improving the error message clarity.The implementation correctly disables the RPOPLPUSH command when cache mode is enabled with list structure, aligning with the PR objective. However, the error message could be more descriptive.
Consider this more descriptive error message:
- res_.SetRes(CmdRes::kErrOther, "the command is not supported when cache&list is enabled"); + res_.SetRes(CmdRes::kErrOther, "RPOPLPUSH command is not supported when cache mode is enabled with list structure");

787-790: Verify consistent error handling across similar commands
Let's verify if this change is consistently implemented across related commands and if there are any other occurrences of RPOPLPUSH that need similar handling.
✅ Verification successful
Let me gather more specific information about the RPOPLPUSH implementation and similar list commands.
Let me check one more aspect to see how other list commands handle cache-related operations.
Cache mode check is unique to RPOPLPUSH and appears to be correctly implemented
The verification shows that:
- The cache mode check is specifically implemented for RPOPLPUSH command, which makes sense as it's a complex atomic operation involving two lists
- The error handling is consistent within the RPOPLPUSH implementation, with similar error messages in both DoInitial() and ReadCache() methods
- Other list commands don't have similar restrictions, which is appropriate as they are simpler operations that can work with cache

更新：暂时不合并本PR，尽量在cache模式下实现rpoplpush即可，并不是一定要禁用。
本PR修复 ISSUE #2953 , 在cache模式下禁用了rpoplpush命令。
